Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
